The most significant difference lies in the abilities that the eye bone and pupils grant Quan Yi, which are distinct from the Crimson Dragon Horn.
For ease of distinction, Quan Yi collectively refers to the changed eye bone and pupils as the Crimson Dragon Eyes.
The abilities of the Crimson Dragon Eyes are divided into two types.
One is the basic ability.
The Dragon Eyes give Quan Yi inhuman resolution, ultra-long-range vision, and terrifying dynamic vision.
With these Dragon Eyes, Quan Yi possesses extremely high operability in combat and other activities.
Through experimentation, Quan Yi can easily manipulate the Crimson Dragon Eyes, easily switching between long-range vision and magnified microscopy.
In addition to Super Vision, the Crimson Dragon Eyes also possess a perspective that can see energy.
This ability is like an X-ray machine, allowing one to see the energy hidden within things.
Just as Quan Yi can see the soul power within Dugu Bo's body, this ability gives Quan Yi the power to see through all appearances.
Quan Yi named this ability the Eye of Truth.
Judging from the ability to see through the soul power within Dugu Bo's body, the upper limit of this ability is very high.
Under the gaze of the Crimson Dragon Eyes, Quan Yi can see the energy fluctuations of the surrounding herbs and poisonous plants.
From Quan Yi's perspective, he can see the medicinal garden emitting colorful energy radiance.
Moreover, what is even more amazing is that the tiny flowers and plants contain vast energy. According to the brilliance of the light, Quan Yi can even see the difference in grade.
More importantly, the object of the Eye of Truth is not limited to living things; it can also see through the energy inside objects.
Quan Yi realized this by observing the soul-guiding iron pot.
The thermal energy stored inside the iron pot is displayed in his eyes in the form of red fluorescence.
This discovery immediately made Quan Yi realize one thing.
That is, soul-guiding devices.
Since he can see the form of energy flow, it is not too difficult to see through the energy structure of soul-guiding devices.
Immediately, Quan Yi picked up the Heart of Scorching Sun and activated the Eye of Truth.
However, the ever-victorious Crimson Dragon Eyes could not see through the internal energy after encountering the Heart of Scorching Sun.
Even if Quan Yi repeatedly took it out and put it in, his Crimson Dragon Eyes could not see through it.
Quan Yi did not expect that his Crimson Dragon Eyes would encounter such a strong opponent as soon as they debuted.
Quan Yi input mental power and soul power into his eyes at the same time.
A faint golden firelight ignited in the golden dragon eyes, which was a manifestation of mental power and soul power turning into substance.
A terrifying wave was brewing in the firelight. The next moment, the dragon eyes shot out golden rays, shooting towards the Heart of Scorching Sun.
The golden light is not sunlight; it carries terrifying penetrating power and possesses physical and spiritual double damage.
The golden rays shot into the Heart of Scorching Sun, but the cold metal seemed unaffected, easily resisting his sight.
"Zzz~."
Quan Yi exerted the Eye of Truth to the extreme, and his eyes gradually ached due to the strong energy fluctuations they endured.
More than a minute later, tears flowed from the corners of Quan Yi's eyes due to the pain.
But the Heart of Scorching Sun did not change at all.
Quan Yi, who was about to reach his limit, stopped outputting.
Quan Yi wiped his red eyes and tears and sighed, "This thing is indeed not simple."
The True Sight Ray of the Crimson Dragon Eyes is a perspective ray specifically designed to see through high-level items.
When Quan Yi's Eye of Truth encounters an item or person that cannot be seen through, the True Sight Ray will help him break through the surface defense and directly see the internal things.
It is a very domineering skill.
However, this skill has no way to deal with the Heart of Scorching Sun.
This shows the extraordinary nature of the Heart of Scorching Sun.
Seeing that the experiment was fruitless, Quan Yi hung the necklace back around his neck.
The secrets of the Heart of Scorching Sun are not something he can窥探 at his level.
After testing the abilities of the Crimson Dragon Eyes, Quan Yi took out the soul power testing crystal.
Quan Yi input soul power into it.
The next moment, the light shone.
Quan Yi's soul power level was fixed at sixty-fourth level.
Seeing that his level had increased by two levels overnight, Quan Yi couldn't help but sigh, "This spring is really my treasure land."
After the external soul bone completed its second evolution, its quality increased significantly.
The Crimson Dragon Horn and Crimson Dragon Eyes not only enhanced Quan Yi's physical fitness and mental power but also improved Quan Yi's soul power level.
At Quan Yi's current cultivation speed, it would take at least a year or so to increase two levels.
This shows why external soul bones are rated second on the Soul Master Dream List.
After Dugu Bo left, Quan Yi was the only one left here.
In the following month or so, Quan Yi cultivated, observed the flowers and plants in the medicinal garden, fed the Nine-Section Emerald, and studied soul-guiding devices.
He spent a very fulfilling daily life.
During this period, Quan Yi would also use his powerful flying ability to travel back and forth between the two places.
After his strength improved, Quan Yi's flying speed increased again. Quan Yi could reach a distance of more than 2,000 kilometers in just over an hour.
Therefore, Quan Yi can decide where to spend the night as needed.
During this month or so, Dugu Bo was busy searching for a suitable soul bone.
If he were just casually looking for a soul bone, with Dugu Bo's strength and status, it wouldn't take him so long at all.
However, considering the compatibility and age of the soul bone, even Dugu Bo spent more than a month.
During this month or so, he searched and studied plans, and he didn't even return to his medicinal garden.
Fortunately, hard work pays off. More than a month later, Dugu Bo finally found a suitable soul bone.
Tiandou City, Dugu Bo's villa.
"Grandpa, why did you suddenly call me here today?"
Inside a spacious room in the villa, a girl with the same green eyes as Dugu Bo rushed into Dugu Bo's arms and acted coquettishly.
This girl is Dugu Bo's granddaughter, Dugu Yan.
Today was supposed to be Dugu Yan's school day, but she was suddenly called back to her residence by Dugu Bo.
This made Dugu Yan happy and confused at the same time.
Dugu Bo lovingly stroked Dugu Yan's short hair and replied, "Yan'er, Grandpa has brought you a gift today."
As he spoke, he took out a wooden box from the soul-guiding device and handed it to Dugu Yan.
Dugu Yan was not polite and took the wooden box while saying, "Thank you, Grandpa, but what gift is so urgent?"
Dugu Yan took the wooden box and opened it. She saw a soul bone glowing with green fluorescence lying in the wooden box.
Dugu Yan's eyes suddenly shone with surprise. She hurriedly covered her mouth with her hands and said, "This is a soul bone! Grandpa, is this for me?"
Of course, Dugu Yan knew what a soul bone was, and at the same time, she understood how rare this soul bone was.
She looked at Dugu Bo in disbelief. Dugu Bo nodded affirmatively and said, "This is the right arm bone produced by the Ten-Thousand-Year Mandala Snake. It is a gift from me to you."
